量化结果差异咨询

作者你好，基于llama 2-7B模型
wikitext-2：量化前：5.47（和论文一致），**W2A16量化后10.22（论文写的9.74）**。W4A16 量化后5.70（和论文一致）
想请教一下，W2A16量化后的差异可能是因为什么原因导致的呢？我所有的参数都是采用默认值~

The report compares Llama 2-7B W2A16 and W4A16 quantization results on wikitext-2 using default parameters, but names no files, tests, or entry points. Start by reproducing the reported W2A16 result with the repository's default workflow and compare it with the paper's evaluation setup. Done means identifying and documenting the cause of the 10.22 versus 9.74 discrepancy.
